My 2003 Trailblazer was put on scanner and given code PO107. What is this and what does this affect?

MAP sensor issue. There is a bulletin from GM about the wiring near the computer rubbing through to metal making the sensor ground out when it shouldnt. Could just be a faulty MAP sensor though. MAP sensor is a very important one in that it tells the computer how much fuel to add or take away due to running conditions, so it could possibly leave you stranded.
